Do you ever have a tune go around in your head for hours

"I'll be home for Christmas". It's not only played every hour on the hour on television, on the Shriner's Children's hospital commercial, but I also read that it was banned in England during WWII as too morbid.

I once heard 'Raining Tacos' and find myself singing it at random moments. Tacos aren't even a big deal in England, but the tune lives in my head.

The worst for me was the Tom, Dick or Harry musical number in the film Kiss Me Kate, it was playing non-stop when I had insomnia, a killer dual punch in the gut!!

Often.

Earworms can be quite annoying, after Barbie Girl came out I couldn't unstick it for days, same with Macarena.
